Today I am going to make awesome sound generator circuit using RGB LED and BC547 transistor. This circuit gives sound like as bicycle horn.
Let's get started,
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Take All Components As Shown Below
Step 2: Connect 330 Ohm Resistor to the Transistor
Firstly we have to connect 330 ohm resistor to the transistor as solder in the picture.
Pinout of BC547 transistor : - Pin-1 is collector, Pin-2 is base and pin-3 is emmiter pin.
# Solder 330 ohm resistor between base pin and emmiter pin of this transistor.
Step 3: Connect RGB LED
Next we have to connect RGB LED to the circuit.
Solder +ve leg of RGB LED to collector pin and
-ve leg to base pin of the transistor as you can see in the picture.
Step 4: Connect 100 Ohm Resistor
Solder 100 ohm resistor between +ve & -ve pin of the Buzzer as solder in picture.
Step 5: Connect Buzzer to the Circuit
Next Solder -ve pin of buzzer to collector pin of the transistor.
Step 6: Connect Battery Clipper Wire
Next we have to connect battery clipper wire to the circuit.
Solder +ve wire of battery clipper to +ve pin of Buzzer and
Solder -ve wire of battery clipper to emmiter pin of the transistor as you can see in the picture.
Step 7: Circuit Is Ready
Now our amazing sound generater circuit is ready.so connect battery to the battery clipper.
Result : Buzzer gives sound like as bicycle horn.
this type we can make amazing sound circuit using BC547 transistor and RGB LED.
